Monitor moving on its own

Did you try any other device on the same plug?

Sounds like there is an issue with the power coming in or there is a problem with the internal power system have you tried any other montiors on the power generator?

NO PC stated, NO OS STATED, must we guess it all?

the last running CRT monitor on earth fail 17 years old.
how amazing, no:?
lost the manual you did, google finds is if you had tried.
the OSD menu, works. push mon. menu button
turn off the sleep timer
RTM always works why not do that.

read the manual
your MON is so old its before modern VESA spec sleep modes were invented,
so it had this silly feature called the sleep timer, with clock
yes has a clock too, crazy no?

page 6pdf.
tells me it does have vesa mode, sleep off the sync pins
on the same page this old relic,has DDC modes
but only work on moden PC< DDC uses a pin that was never used before on the VGA jack.
that same page also states, DDC2Bi (plug and play) only works on MONItgor jack B..

so note tell me your PC or its video card model if used.
or whaT this is (windows95.)>?'
we cant help much can we.
but you can test your monitor on another PC.
if that fails, the monitor is bad
but you must try both MON, rear VGA ports.

if the PC was dead, i sure can be.
youd have tried another barrowed monitor to prove that.
easy.

Take it to a service shop and ask them to open the unit and the display. The cable connector to the display is loose on one side.

u must click on any button on the screen and try to control one by one till u find the destination which u want

Assuming you are using Windows Vista:

All you have to do is connect your laptop to a monitor via a VGA port (located on either the side or at the back of your laptop - it's the port with about 15 holes).

Once connected , you will need to configure how your 2nd monitor will function - as an extended or duplicate monitor. To set this you will need to go to Display Settings > and select your option.

Any time you have a orange light . The monitor or video card can be at fault. First check the monitor. Turn it on and see if it goes from green to amber. Check all monitor cable connections. to make sure the all 15 pins are there . If monitor displays a message that check video signal most likely video card is the problem. Make sure you have the cable connection plugged in the back of the computer into the video card. Usually a picture of a monitor. Then afterwards turn the monitor on first then the computer. If you do the other way around then the video card most likely will not engage.

Try moving the cable that goes into your graphics card i had a connection problem with mine, i either moved my tower or the cable to correct the problem

If that monitor is out of warranty, it's pretty much a throw away item. If you can find a "donor" monitor with a cracked CRT or case, you could probably swap the high voltage units and get it going again.

I suspect that when you reattached the monitor back you might have moved the agp card out of her slot. Check if you have connected properly your monitor to the pc And if the agp is in it's slot properly attached. Hope it helps, good luck!!
